Hi,
Im trying to remove the refraction applied by invisibility spells -- in order to patch an issue with my mod -- but I can't for the life of me work out how!

This guy: http://skyrim.nexusmods.com/mods/10494 has worked out a way but he's been inactive since may.

I've removed all Visual Effects from the Magic Effect with no luck.
I think it's in the Effect Archetype "invisibility", what is that, and where do I edit it?
